1) The procedure was applied on 28 patientes, 16 of which were females and 12 males ranging between 25 and 71 years of age. In 17 cases splenic percutaneousapproach was employed, in 10 repermeated umbilical approach and in one case the approach was ileal intraoperatory. 2) After determining portal pressure, hydrosolublecontrast was used in detecting possible azygo-portal or porto-cava communications or bivenous shunts (portasuprahepatic), for in this case the method is contraindicatedTwenty ce. of were injected and became apparent three phases: portal, sinusoid and hepatic. The latter had been described by the. author in 1969 from the radiological angle.3) Radiocinematography, performed in 6 patients, brought out new facts of portal hemodynamics, indicating the possibility of measuring circulatory speed. 4) We analyzed the results obtained during the different intra and juxtahepatic expansive processes and the procedure proved to be efficient and inocuous. Two nodules ½ cm. in diameter were observed. It also proved to be efficient in post-operatory control of the adventitions hydatid cavity, as well as in studyirtg local circulatory condition in compensatory hepaticatrophies or hypertrophies. 5) Hystological study 10 patients indicated that the hepatic phase described in radiological observation was present. The lipidic excess in the hepatic celland in Kupfer's cells was observed, as well as its subsequent dispersa! and fragmentation; no other citoarchitectural alterations were observed. 

In 70% of traffic accidents, head trauma occurs (11) and one in three victims is a multiple trauma patient (12).

This experiment was carried out with 33 patients who underwent high biliojejunal anastomosis with theHivet-Warren loop. Twenty-eight of these patients were suffering from obstructive cancers in the biliary trae! and five had stenosis or benign fistulas. None of themshowed clinical symptomatdogy that could be ascribed to complications derived from this technique. However in three cases, who had to be reoperated five monthslater for differents reasons the afferent branches which had been ligated were found to have been repermeabilized. In another patient, a large asymptomaticblind pouch had been formed above the stricture  the paper analyzes the advantages, inconvinients and indications of the Hivet-Warren loop and the technicalvariations for preventing complications.

The paper contains an evaluation of the treatment applied in 110 cases of malign melanoma with a recovesypercentage of 17 .1 % , The best results were obtained throigh the association of surgery and chemiotherapy by perfusion, but this latter procedure is reserved for lesions in the limbs.

Out of 59 reno-ureteral traumatisms registered in the University Hospital (Hospital de Clínicas), we find two cases of ureteral traumatic lesions, one ofwhich was due to a bullet wound, and the other, in our understanding the most serious, was an internal traumatism. The paper describes their clinical aspects and refersto the value of urographic studies in deterning the lesion. However this method should be completed by ascending pyelography. Pathogenesis and treatment are considered and theauthor includes a review of authors who have referred to this type of lesion.

The paper contains a brief summary of the anatomy of the umbilical vein and the technique employed inits repermeation. The procedure is simple and inocuous. It is used as approach to the portal system umbilicoportógraphiesa and oleohepatographies, thus avoidingthe "splenic macula". The method was employ.ed on 13 patients, successfully in 10, the remaining 3 being failures.

The authors have made a brief compilation of pathological and clinical aspects of subphrenic retroperitoneal abcesses, including two case histories. The paper contains the anatomical review thereof.

The paper presents splenoportography and kinematic study through cineradiology in the evaluation oZ circulation time in the different syndrome of portalhypertension and introduces anesthesia of the phrenic nerve. Series are rapid and injection is made through automatic pneumatic pump. The normal aspect isshwon and compared with the different obstacles to splenoportal circulation at the different levels: splenic, extrahepatic portal, intrahepatic and suprahepatic.

The paper shows the value of arteriography of the celiac axis in portal hypertension, benign and nalign expansive processes, thoracoabdominal traumatismand in testing the permeability of the splenoportal venous axis when there are doubts as to classic splenóportography.

This topic draws its importance from the fact that any abdominal surgeon may find that the process causing laparatomy is in the genital tract or inthe genital tract there is a concomitant pathological problem whose treatment must be resolved at that time.
